The rules of US politics are being rewritten in this electoral season. The Republican Party has been shaken to its core by the rise of Donald Trump while the Democratic contest for the presidential nomination is really a struggle for the soul of the party. The contest between Hillary Clinton and Bernie Sanders is a choice between the centrist establishment favourite and the self-styled socialist progressive insugent. Congreswoman Donna Edwards from Maryland is a powerful voice on the left of the Party. She's running for a seat in the Senate. But is America ready for genuinely left-wing politics?

HARDtalk speaks to Fahd al Rasheed, CEO of King Abdullah Economic City in Saudi Arabia. King Abdullah Economic City is a vast construction project on the Red Sea. It is supposed to become one of the world’s biggest ports with a population of 2 million – a new global city for Saudi Arabia. But could the kingdom’s economic problems see this dream turn to dust?

HARDtalk's Stephen Sackur speaks to John Cale, a founding member of the Velvet underground, and a solo artist and producer. In the checkered history of rock and roll, there have been relatively few artists who have managed to create a genuinely new, even revolutionary, sound. The Velvet Underground achieved just that in mid-sixties New York - combining youthful anger, musical creativity, with an avant-garde art sensibility. Today John Cale continues to experiment with new sounds. To many, his music is challenging, even bleak, but is that a reflection of the man himself?

From his Oscar winning score for The Lion King, through 12 Years A Slave to a series of superhero blockbusters, including the latest - Batman v Superman - Hans Zimmer is, as one director put it, "quite simply the contemporary composer to work with". German born, British educated, he never received formal musical training and he's a champion of technology. Hardtalk’s Shaun Ley asks Hans Zimmer whether the technology he so loves is killing the music makers?

The United States is beefing up its military presence in Europe. Hardtalk asks Russia's Ambassador to the EU if the Kremlin can sustain a long-term confrontation with the West?

The suicide bomb attacks in Brussels are unlikely to be the final operation mounted by the so-called Islamic State on European soil. France's President Hollande says Europe is now at war, so what are the most effective weapons at Europe's disposal? Dominic Grieve was the Attorney General in David Cameron's first term as British prime minister. He is now Chairman of the UK parliament’s Intelligence and security committee. Can Europe be both secure and free?

Can architecture inspire people to think and behave differently? Hardtalk speaks to David Adjaye, one of the most sought after architects in the world today. Among his many buildings are the Nobel Peace Centre in Oslo, a business school in Moscow, shopping centres in Beirut and Lagos, a children's hospital in Rwanda, a housing project in New York's Harlem, and about to open - his biggest project yet - the National Museum of African American History and Culture sitting right on the National Mall in Washington. Has he got it right? What is the test of a good building?

Nationalist, anti-immigrant parties have made inroads in a host of countries in Europe, for example Hungary, Denmark and Finland. In Finland a right wing populist party, The Finns, is a significant player in a centre right coalition government. Stephen Sackur talks to Timo Soini, their leader and the nation's Foreign Minister. What happens to populists when they are faced with the compromises that come with sharing power?

The Organisation for Security and Co-operation in Europe has its roots in the cold war - it was a unique platform for dialogue between the West and the Soviet Bloc on matters of security and human rights. But that was then, what about now? Hardtalk speaks to Lamberto Zannier, Secretary General of the OSCE. In a new era of tension between Moscow and the West, how much use is his organisation?
